This is a very rare example of the Kerr Patent true double action revolver that will both hammer cock and trigger cock, the vast majority of Kerr Patent revolvers being single (cocked) action only. This particular example was retailed by the famous Scottish gunmaker Charles Ingram. The octagonal barrel has a brass front sight and is signed “CHAS. INGRAM. GUN MAKER. GLASGOW” and struck with London proof marks and the “L.A.C.” mark of the London Armoury Company. The frame is engraved with double border lines and respectively marked on the sides “KERR’S PATENT. 599” and “LONDON ARMOURY”. The lock is also engraved with double border lines and is fitted with a safety catch. Checkered walnut one piece grip and plain cylinder struck with further London proof marks. Blued finish throughout. Kerr revolvers were designed to be repairable in the field by the unit armorer as the lock is very similar to the one fitted to the Enfield rifle-musket.

Fine. The revolver retains 30% original blued finish. The remaining surfaces a dark patina with numerous scattered age related storage and handling marks throughout. The grip has a darkened patina. The mechanism requires attention with a spring pushing against the front portion of the trigger guard causing it to stand proud and the trigger return is not fully resetting after the action is cycled. Mechanically very good.
